With that quite unusual behavier of torque for a petrol engine, it makes sense to shift the gears short, almost like a diesel engine and in combination with a 7-speed gearbox, that could explain, why they have so unusual shifts. |

Its growing on me . Good picture shows how much vision the driver has . Id like to see them ban that big wheel arch on safety grounds .

Will be interesting to see whether Porsche keep those aggressive front fender shapes, Toyota have just toned their's down while Audi have never had that vertical shape at the front like the Porsche does here. You wonder whether it really is the best way to go.
Of course, it may be the best design for the aero philosophy which will be different to these year's cars anyway. The hybrid system will need a lot of cooling I would imagine. |

I did not say that they went full throttle or how they used their hybrid system(s).

Do the front and rear wheels look the same size to anybody else? I thought for 2014 the fronts where going to be a smaller diameter again.

The size is the same relatively speaking. You actually have a greater decrease in width of the car than the wheel width dimensions! 2000mm to 1900mm car width / 14.5" to 13" wheels. Or 3.9 inches decrease car width / 3.0 inches wheel width.

It seems to me, to make an engine like that to be competitive and remain a 7 speed, it would need a really big ring & pinion or drop gears. Since the g-boxes are homologated at the beginning of the season, I don't think you can change cases or gear counts (switching from 7 to 8 in the same case). I would think that to be competitive at Le Mans, Monza, Austin, or Silverstone one would use a square or over square, high rpm engine. The efficiency would come from fuel and boost metering, plenum design (kinda like the early 80's with Motronic), and the hybrid system. I know very little about hybrid systems, most here probably know more about them than me. I'm not an engineer, I was just a mechanic and gearbox guy, but I can't wait to learn more about this stuff. And I can't wait to see this car in person. I'll be in Austin. |

I'm interested to see (though we may never actually know these types of details) how the unknown energy recovery systems will interact with the drivetrain.
I think the regs require constraints around how and when the energy can be released,.... Questions: Could this be synchronized with particular gears or gear changes? Could you have one system (let's say a front wheel flywheel system) just give extra boost on corner exit,.... but then have a rear drive system (enter dangerous banned technology here) that would be sycronized to activate for say only 6th and 7th gear? I don't know jack about gearboxes; but it seems intriguing,.... maybe the secondary system could just be used for fuel economy purposes; but it would seem like some advantages could be gained in this way????? |

If you want to get 4 bar of boost from a 2L 4 cyl engine, you have to rev it high. Rev it high and there is so much friction and so much inefficiency. With no fuel limit might have made some sense, but in 2014 they will have hard time with this unit to get the boost and the fuel numbers, unless you sacrifice one or the other.

On this week's french AutoHebdo they show the Porsche with a Gulf livery. Does it mean something or is it just some random illustration ?
It reads "Porsche 2014, our new info", that's why I'm asking. Last edited by jsTrecu; 4 Sep 2013 at 13:37. |

I think that's a deliberately misleading photoshop job to raise interest. Nothing wrong with it technically speaking - no Gulf logos on that car.

It means they know sports car racing history and understand sports car racing fans.
With Mobil1 sponsorship I doubt we will be seeing Gulf livery. (ExxonMobil to Support 2014 Porsche LMP1 http://www.theepochtimes.com/n2/spor...p1-291663.html) |

That's what I thought, it seemed unlikely.
Thanks |

The 911 GT3 R Hybrid did the orange thing also ... but orange and blue? Seems vaguely reminiscent of some 917s I recall-- well, of which I have seen pictures. I didn't see them race.

And I'm still thinking the major sponsor could be something they have not announced yet. Or more like hoping, because if not even they can secure a major deal, that tells something about the attractiveness of WEC. |

Don't get me wrong, they still might be after a title sponsor but just because they don't have one doesn't mean the WEC is unattractive to sponsors. Must be above the WRC in the pecking order! |

One could say that 918 livery is a Gulf reference...

Bentley example: no WEC back then and probably relatively cheap program compared to current ones. Quote:

I think the WRC being as weak as it is, the going rate for title sponsorship is very cheap... |
